How do you find the equation of a line with two intercepts?
Steps to find the equation of a line from two points:
- Find the slope using the slope formula.
- Use the slope and one of the points to solve for the y-intercept (b).
- Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
How do you write a linear equation in slope-intercept form?
The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It’s usually easy to graph a line using y=mx+b.
How do I find an equation of a line?
To find an equation of a line given the slope and a point.
- Identify the slope.
- Identify the point.
- Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) .
- Write the equation in slope-intercept form.
How do you find the equation of a line with slope and a point?
These are the two methods to finding the equation of a line when given a point and the slope: Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. Use the m given in the problem, and the b that was just solved for, to create the equation y = mx + b.
How do you find the equation of a line given the slope and y-intercept?
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
What is the 2 intercept method?
Definition: The Two-Intercept Form of the Equation of a Straight Line. The two-intercept form of the equation of a straight line that intercepts the 𝑥 -axis at ( 𝑎 , 0 ) and intercepts the 𝑦 -axis at ( 0 , 𝑏 ) is 𝑥 𝑎 + 𝑦 𝑏 = 1 , where 𝑎 and 𝑏 ≠ 0 .

How do you determine the intercepts from an equation or graph?
The y-intercepts are points where the graph of a function or an equation crosses or “touches” the y-axis of the Cartesian Plane . You may think of this as a point with x-value of zero. To find the y-intercepts of an equation, let x = 0 then solve for y.
